REFLECTO-R FORLOCOMOTIVE HEAD-LIGHTS.

SPECIFICATION forming part of Letters Patent No. 414,807, dated November 12, 1889.

Application filed May 15, 1889. Serial No. 310,374. (No model.) A

To @ZZ whom, it may concern.-

Be it known that I, ELiAs O. GLAZ1nR,a-eiti Zen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented .new and useful Reflectors for Locomotive Head-Lights, of which the` following is a specification.

rlhisinvention relates to reflectors for locomotive head-lights; and it consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure l is a perspective view of a locomotive head-light having a refleet-or embodying my invention. Eig. 2 is a vertical transverse sectional view of the same. Fig. 3 is a perspective view showing the rellector detached from the lantern-casing. Fig. 4 is a longitudinal vertical. sectional view of the same. Fig. 5 is a perspective viewshowing the parts of the reflector separate or detached from each other. Fig. 6 is a view showing the sections of the reflector connected adjustably by means of a hinge-joint.

The same lettersrefer to the same partsin all the gures.

Rellectors for head-lights have heretofore customarily been manufactured by beating` them out of a single piece of metal, a process which,owing to their peculiar shape and size, has been troublesome and costly.

My improvements consist, primarily, in constructing the reflector in two sections, designated in the drawings by A A, and which, when placed together edge to edge, form a reflector-body of the usual parabolical shape. The sections A A are provided along their front or outer edges with flanges B, and the must be connected in such a manner as to leave their meeting edges a suitable distancesay about th ree-eighths of an inch-apart,thus

lforming a slot of that width in the reflector,-

through which the same light which serves to illuminate the reflector will illuminate the said transparencies sufficiently for all practical purposes. The sections A A may be connected in any suitable manner which may a be found most desirable and convenient. Thus 7o the flange C of one of the sections may be provided with bolts E,extending through the other section, washers F of suitable thickvness being interposed between the two secftions for the purpose of making a slot or 75 space of the desired width.

Another method of connecting the two sections is shown in Fig. 6 of the drawings, where Ethe sections A A have beenl shown to be connected at their apices by means of a hinge- 8o joint G, uponwhich the upper section may swing. The hinge-joint is so constructed as to leave the apices of the sections A A the desired distance apart, and lugs or studs H are placed upon the flange C of they lower section A, near the front end thereof, for the purpose of properly spacing the said sections. A cord I is attached to the uppersection A and passed through the lantern-casing and over suitable guides or pulleys to the engineers cab. It 9o will be seen that when the reflector is thus arranged the light will normally shine through the slotor space between the sections A A, and thus serve to illuminate the transparent signals in the sides of the lantern-casing,while at the same time the light of the lantern is reflected or thrown in a forward direction in the usual manner. -lVhen it shall be desired, however, to cause the reflector to stop throwing the light in a forward direction, this may roo be effected by raising the upper section A upon its hinge to an approximately vertical position, When the forward reflection of the light will be Vdestroyed without impairing the illumination of the signals in the sides of the lanterircasin g.

By constructing the reflector in the manner herein described it may bemanufactured at a much reduced expense, and Ihave found by experimenting that the reflector may be constructed in this manner without impairing its power in the least, the horizontal open p ing or space between the two. sections heilig quite invisible at a short distance. At the same time I have found that the light emitted through the said slot or opening is amply suflicient to illuminate the transparencies in the sides of the lantern-casing wit-hout the assistance of supplementary lights or sulrretlectors.

lVhile I have herein described the preferred construction of my improved reflector, I would have it understood that I reserve the right to make any alterations in the details of the construction which practice may prove to be expedient.

Having thus described my invention, I claiml. A reflector for head-li ghls, constructed of sections divided on a horizontal longitudinal plane, substantially as set forth. 2. A `parabolical reliector for head-lights, constructed of sections divided on a longitudinal plane and so connected as to leave a space or opening between the meeting edges of said sections, substantially as set forth.

3. A reflector forhead-lights, constructed of separable sections having flanged meeting edges and connected to leave a space or opening between the said meeting edges, substantially as set forth.

et. A reflector for head-lights, the body of which is divided horizontally and longitudinally, the sections composing the said body being connected separably with their meet-- ing edges a suitable distance apart, substantially as set forth.

5. A reflector for head-lights, constructed of lon gitudinallydividcd separable sections connected by a hinge-joint, substantially as set forth.

6. A reflector for headlights, constructed of longitudinally-divided separable sections hinged together, in combination with lugs or studs arranged to hold the meeting edges of the said sections a suitable distance apart, substantially as set forth,

7. A"parabolieal reflector for head-lights, constructed of separable sections divided ou a longitudinal horizontal plane and hinged together, in combination with a cord attached to the upper section and passing through the lantern-Casin g and over suitable guides to the engineers cab, substantially as set forth.

8. The combination, With-a lantern-casing the sides of which are provided with transparent signals, of a parabolical reflector constructed of separable sections divided on a longitudinal horizontalI plane, connected to ileave a space or opening between the meeting edges of the said sections, substantially as set forth.

9. The combination, with a lantern-casing provided with transparent signals, of a rcflector constructed of separable sections hinged together and held normally apart to admit of the passage of light to illuminate such signals, substantially as set forth.

l0. The combination, with a lantern-casing having transparent signals, of a reflector constructed of separable sections hinged together, and a cord attached to the upper hinged section and passing through the lantern-casing and over suitable guides to the engineers cab, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
